Oracle Data Source in Enterprise Gateway
I'm having trouble adding an Oracle database as a data source in the enterprise gateway. The error message I get is below:
Unable to connect: We encountered an error while trying to connect to SERVER_NAME. Details: "Cannot connect to the mashup data source. See error details for more information."Hide details

I can confirm that I have the latest ODAC components installed on both the client machine and the server where the enterprise gateway is installed. I have also tested connecting to the data source through Power BI Desktop and it works just fine.
Any ideas? Thanks.
Hi dimazaid, I managed to solve this by using the Oracle service name found in tnsnames.ora instead of using the full hostname.
So instead of putting "HOSTNAME" in the "Server" field, all I had to do was put in the service name. For reference, the syntax of a tnsnames.ora entry is:
SERVICENAME =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TYPE)(HOST = HOSTNAME)(PORT = PORTNUM))
(CONNECT_DATA =
(SERVICE_NAME = SERVICENAME)
)
)
Thanks, I forgot to mark this one as solved!
